4CAN-Hsatinata MACHINE.

SPECIFICATION forming part of Letters Patent No. 540,366, dated J' une4, 1895.

Application filed April 24, 1894.

To 1f/ZZ whom, t my'concern:

Be it known that I, HENRY SCHAAKE, aoitizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inCan-Heading Machines; and I do hereby declare the following to be afull, clear, and exact description of said invention, such as willenable others skilled in the art to which it most nearly appertains tomake, use, and practice the same.

This invention relates to a certain new and useful machine for applyingtight fitting heads upon the outside of the ends of can bodies, or tothat class of machines known as outside headers, which consists in thearrangement of parts and details of construction as will be hereinaftermore fully set forth in the drawings, described and pointed out in thespecication.

The present invention has for its object to accomplish mechanicallythework performed in the can heading device secured to George A. Marsh byLetters Patent of `the United States No. 152,757, granted on the 7th dayof July, 1874; that is to say, that by the machine herein shown anddescribed the can head is applied to the can body by causing one end ofthe can body to be first inserted within the ange of the can head at anangle thereto, after which the body is gradually brought into ahorizontal position, which causes the end to be headed to be tilted orforced over until the entire circumference o f the can body has enteredwithin the flange ot the can head, which applies one head to thercanbody, after which the opposite or free end of the can body is likewisetilted or moved into the iange of the opposite can head, the can thus`being' headed in the same manner as described in the Marsh LettersPatent No. 152,757, the difference being that by the use of tho presentmachine the can body is placed within the flange of the can headautomatically or mechanically, whereas in the Marsh patent, aforesaid,the can body is forced within the flange of the can head by hand, theMarsh device being a mere hand tool, while the present invention is acomplete operative machine designed to place a tight fitting exteriorhead upon can bodies with rapidity.

Serial No. 5 0 8.8 5 9. (No model.)

In both the Marsh hand tool and the present machine the body is appliedto the can head by first placing a portion ofthe outer edge of the canbody within the fiange of the can head at an angle thereto and thencetilting the can body over until the entire circumference of the body isforced within the flange of the can head.

In order to more fully understand my invention reference must be had tothe, accompanying sheets of drawings, wherein- Figure 1 is a sideelevation of the machine, showing only a limited number ofcan-bodyclamping jaws. Fig. 2 is a side elevation of one of the slottedcam-plates for raising and lowering the clam ping-jaws. Fig. 3 is an endelevation of the machine viewed from the feed end. Fig. 4 is a top planView of' the slotted plate for imparting lateral movement to thecan-body-clamping jaws, so as to place the end of the retained can-bodywithin the flange of the can-head. Fig. 5 is an enlargedid'etailed viewof one of the links or frames which constitute the endless carrier andone of the clamping-jaws for the can-bodies. Fig. 6 is a view similar toFig. 5, showing position of the can-body-clamping jaw when tilted orswung so as to place the lower edge of the can-body within the flange ofthe cau-head.

Fig. 9is a detail top plan of one of the can-head holders or seats. Fig. 10 isa detail View of the canbody-clamping jaw closed. Fig. ll is a similarView of the can-body-clamping jaw when open. Fig. 12 is a detail sideelevation of one of the retaining plates, blades, or paddles for theretained can-body, shown in a lowered position. Fig. 13 is a similarview of the plate, blade, or paddle when in a raised position. Fig. 14is a top plan view of one of the links or frames constituting theendless carrier-chain. Fig. 15 is an enlarged side view,

in elevation, of the segment-cam for opening ICO , may be cast integralor separate as desired.

These plates or side pieces may be said to constitute the frame of themachine.

Between the side plates or frame I locate the disks or wheels C, C,which are secured upon the cross shafts or axles B2, B3, one at each endof the frame, as shown by Fig. l. The forward shaft B2 constitutes thedrive shaft, it having secured to the outer or projecting end thereofthe belt wheel C2, which is driven by means of a belt pulley. Not shown.

Over the wheels C, C', travels the endless carrier chain or belt whichconsists of a series of rectangular open frames united together. Theseframes each carry clamping jaws for the can bodies.

One of the rectangular open frames is pro vided with a male section of ahinge joint, c, while the opposite one is provided with a femalesection, c', which sections, when fitted together, are united by a boltc2.

In order to' provide for a positive travel of the endless carrier beltor chain and prevent slipping thereof, I cast the disks or wheels C, C',of a heXagon-'shape, thereby providing a series of faces b', each ofwhich is separated by the notch b2, within which notched portion theknuckles ofthe hinged joint of the frames of the carrier chain lit orrest while the frames bear upon the flattened faces of the disks orwheels C, C.

From the ends of the truck frame project the pins c3, upon which aresecured the rolls h. These rolls work within the channels or guidegrooves ct cut within the inner face of the side pieces A', A2 of theframe and serve to support the endless carrier chain or belt whiletraveling between the carrier wheels, and bear upon the flanges ct ofthe curved end pieces, after leaving the guide grooves or channels, thusacting as supports for the truck frames of the endless carrier belt orchain. These open frames, which when hinged together constitute theendless carrier chain or belt, have the dovetailed grooves d out withinthe inner face and crosswise thereof, within which tit and work theslide frame D, see Fig. S, said frame being an open one and rectangularin shape, but smaller in size than the opening of the rectangular frameC3, so as `to permit of lateral movement.

Within the rectangular slide frame I cut four openings d', through whichwork the rods D', D2, four in number. These rods are connected in pairs,at their top, by the brackets D2, Dj, at their lower ends by plates E,E. These rods have a vertical movement, but each pair move independentof the other. In order to secure a long bearing for the rods D',

D2, I secure to the frame D, the bosses e, through which the rodsextend, as shown in Fig. '7. j

Within the brackets D3, D4, there is hung, by means of trunnions e', ethe swinging frames E2, E2, which frames are provided with thedownwardly extending hollow sleeves F, F. 'lhesc swinging frames areprovidedl with inwardly projecting hollow bossesf, between which thesections F2, F3, of the clamping jaws are secured by means of the boltF4. The lower end of each jaw section is connected to the vertical rodG, by link c, thus forming a toggle joint connection. The rod extendsdownward through and below the open slide frames D, and serves to openor close the sections of the can body clamping jaw as raised or lowered.

Through the hollow sleeves F, F work the vertical rods Si', G2, theupper ends of which rods terminate in a plate, blade or paddle G3, G4.These plates, when raised, bear against the end of the can body,retained within the can body clamping jaws, and prevents thedisplacement thereof during the operation of placing a head upon thebody. These plates may more properly be termed can body retainingplates, blades, or paddles. The rods raise and lower alternatively. Saidrods are so placed within the hollow sleeves as to permit of a directupward movement until the retaining plates, blades or paddles carriedthereby have passed beyond the lower surface or edge ofthe can body,after which they gradually move inward until the end of the can bodyopposite to that about to receive a can head is engaged by the retainingplate. This is necessary, for did the plates, blades, or paddles movetheir full lift in a direct line they would have a tendency to catch thelower edge of the projecting portion of the can body, for the reasonthat the can bodies do not always seat themselves in the same placewithin the clamping jaws. However by providing for the plates, blades,or paddles being carried above the lower surface of the can body priorto engagement therewith this diiculty is overcome. This second movementof the rodsG, G, which throws the can body retaining blades, paddle orplates, is accomplished by providing the hollow sleeves with theinclined shoulders g', g2, which are engaged by the inclined lugs 7i.,h', projecting from the said rods.

After the rods have been lifted a given distance, sufficient ,to causethe retaining plates, blades or paddles to clear the edges of the canbody held within the can body clamping jaws, the inclined lugs ride uponthe inclined shoulders and thus force the rods moving upward toward theprojecting ends of the can body held within the can body clamping jaws.The rods when raised are held in their lifted position by the pressureof the springs G5 thereagainst, which springs are secured within thehollow sleeves. See Figs. l2 and 13.

Bysecuringtheclampingjaws within swing- IOO IIO

ing frames I permit the jaws to be tilted or swung at an angle to thesliding frame without the necessity of said frame'being tiltedtherewith. As will be noticed by reference to Fig. 6, the clamping jawsfor the can body are so secured to the frame as to permit of the sameswinging upon an axis horizontal to the said sliding frame.

From the plates Ior bars E, E which connect the lower end of the liftrods, outwardly project the arms H, H. These arms work within theshouldered slots of the cam plates H2, H2. These cam plates runparallel, a distance apart, as shown, and are supported by means of theshafts B2, B2. Inasmueh as the slots within which the arms H, H traveleX- tend the entire length of the said cam plates, it is necessary thatthey be cast with the ribs H.4 in order to unite the sections of the camplates, else the cam plates must be cast in sections and the ribsriveted thereto. It will be noticed that the slot in each plate is madeso that as one arm is elevated, so as to raise the lift rods on thatside of the machine, the

opposite arm is lowered.

Referring to the plates H2, H3, see Figs. 1 and 2, it will be observedthat from point 1 to 2 the slot of each cam plate is upon a level, sothat when the arms H', H2 travel within this portion of the slotted camplates the clamping jaws for the can body, and connecting parts, will beelevated to the position illustrated by Fig. 5. From point 2 to 3theslot of cam plate H2 is cut upon a downward incline from point 3 to 4upon a straight line or level, from pointf1 to 5 upon an upward incline,from 5 to 6 on'a level orstraight line, from 6to 7 at a slight downwardincline, from 7 to 8 on a level or straight line, from 8 to 9 at anupward incline, from 9 to 10 ona level, from 10 to 1l ata downwardincline and from 11 to the end of the cam plate on a level or straightline, while the slot in cam plate H3 from point 2 to 12 is run at anupward incline, from 12 to 13 on a level, from 13 to 1-1 at a downwardincline, from 14 to 15 on a level, from 15 to 16 at a downward incline,from 16 to 17 on a level, from 17 to 18 atan upward incline, from 18 to19 on a level, from 19 to 2O at a downward incline and from 2O to end ofthe cam plate on a level. It will thus be noticed that the slot in camplate H3 is run very nearly the opposite of that of the cam plate H2.Consequently when one set of lift rods is raised or elevated by the armsthereof traveling within the slot of one of the cam plates, the oppositepair of lift rods will be lowered.

From the rectangular frame C3 upwardly extend the curved arms I, I,theends of which terminate in a semicircular can head seat or holder I2,l2. Within the upwardly projecting shoulders 14,15, I cut an elongatedopening 7L, through which projects the bolts 7L, h4, by means of whichthe upper ormovable half I, I7, of the can head holder is secured. Thebolts h, h4 carry the rolls h2, h2, which raise the movable section ofthe can head holder as hereinafter set forth. The movable portion of thecan head holder has a semi-circular can head seat or socket cut in therear face thereof, which, when the said section isl lowered, conformswith the semi-circular seat or socket cut within the lower section andserves to complete the annular seat for the can head.

The outer face of the movable sections of the can head holder I cut awayor chamfer, as shown at k, so as to permit the upper edge of the canbody -to be gradually gathered in as the projecting end of the body isforced within the flange of the can head retained within theannnlar seator socket of the can head holder. In this respect, that is, theproviding a semi-circular chamfered plate for guidance of the end of thecan body within the flange of the can head. my seat is the same as thatset forth in the Marsh hand tool or device covered by Letters Patent No.152,757.

Within each movable section of the can head holder I cut the opening7a4, which permits the heads dropping from the can head feed chutes K, Kdirectly into the can head or socket of the can head holders. Themovable section of the can head holder I2 is raised as the forwardmovement of the endless carrier carries the roll h2 up the inclined faceof fixed cam K2, held in line therewith by curved bracket 7c3, securedto the frame of the ma chine. See Figs. 1 and 3. The movable section ofthis can head holder is held raised until said roll has traversed'thelevel portion of the said cam, during which travel the headed end ot'the can body is withdrawn from within the can head holder. As the rollmoves Voff the opposite end of the cam, which is downwardly inclined,the movable section is gradually lowered or closed.

To one side of the machine I secure the slotted plate J, which plateruns the entire length of the machine and the slot therein is s0 cutthat the roll j, secured'to the downwardly extending pin j projectingfrom the sliding frame D, during its travel therein will serve to shiftthe sliding frame D from side to side of the rectangular frame of theendless carrier in accordance with'which end of`the can body is beingheaded. As will be noticed this slot runs from point 2l to 22 in astraight line, thence-at an outward incline to point 23, thence in astraight line to point 24, thence at an inward incline to point 25,thence in a straight line to point 26, thence at an 'inward incline topoint 27, thence in a straight line to point 2S, thence at an outwardincline to point 29, and from there to the end of the plate in astraight line.

At each end of the machinel locate the segment shaped cams L, L', theformerof which is keyed to the shaft B2, which extends through itshub,Fig. 3. The shaft B2 isa non-rotating one, the disks or wheels at` thefeed end of the machine being loosely. securedupon said shaft. Segmentcam L is located at the IOC Ito

forward end of the machine', the drive shaft B2 passing through the hubL4 thereof, which is bolted to the flanges Z4, Z5 projecting from thehubs L5, L6, respectively, of the slotted cam plates H2, H2, throughwhich hubs extends the shaft B2. Fully shownin Fig. 16. As the roll Z,laterally projecting from the rod G, is carried over the inclined faceof the segment cam L, during the travel of the endless carrier chain,the rod G is raised, which closes the clamping jaws `around the can bodyL2, fed therein from the feed chute L2. As the clamping jaw is carriedover the disks or wheels secured' to the drive shaft B3, after the canbody has been headed, the roll Z is carried beneaththe flange m inwardlyprojecting from segment cam L', which gradually draws the rod G downwardand opens the clamping jaws-so as to discharge the headed can body intothe runway M. The clamping jaws are opened and closed through themedium'of the toggle joint connection before described. y

After the clamping jaws have been closed around the can body in order totrue and round the same so as to correspond to the interior diameter ofthe can head flange, it becomes necessary that the clamping jaws withthe ends of the can body projecting there'` from, be raised so as to bein line with the flange of the retained can head M This rais ing of thecan body is accomplished through the medium of the lift rods D', D2, asthe arms H', H, projecting from the connecting plates E, E work withinthe slotted cam plates H2, H2. As the arm H travels from point 2 to 3the rods D are lowered, which carry that side of thecan body clampingjaw therewith, while the rods D2 are raised by the arm H traveling overthe upwardly inclined portion of slotted cam plate H2, or between point2 and 12. This travel of the carrier belt or chain causes the clampingjaws to assume an inclined position to thel can head holder or clamp,as

illustrated by Fig. 6. While the clamping jaws are being swung or tiltedatan angle, the slide frame D is drawn over or forced to slide withinthe rectangular open truck frame by the roll j riding upon the outwardlyin-r clined portion of the slotted plate J, or between the points 22 and23. The drawing over of the slide frame causes the lower edge of theprojecting end of the can body to move within the flange of the retainedcan head. See Fig. 6. Prior t0 the tilting of the clamping jaws the rollm secured to and projecting laterally from lift rod G', rides upon theinclined fixed cam N, secured to plate H2, and forces upward or raisesthe said rod within the hollow sleeve F. This movement of the lift rodcauses the retaining plate, blade, or paddle G2 to move in front of theprojecting end of the can body, as shown in Fig. 6. As the clamping jawsand their connecting parts are carried forward, arm H travels upon thelevel portion of the slotted cam plate H3, or from point 12 to 13, whilearm H travels over the upwardly inclined portion of the slotted camplate H2, or from point 4 to 5, the distance from 3 to 4, or levelportion having been traversed while the frame D was being drawn over inorder to place lower edge of the proj ecting end of can body within canhead flange. As the arm travels upon this upwardly inclined portion ofthe slotted cam plate H2, the right hand side ofthe clam-ping jaws aregradually elevated or raised until the can body assumes a horizontalposition. This raising of' the can body to a horizontal positiongradually tilts or forces the upper left hand edge of the projecting endof the can body within the flange of the retained can head.

After the projecting end of the can body has moved within the flange ofthe can head the roll h2 rides upon the inclined face of the cam K2 andcauses the movable section of the can head holder I2 to move outward soas to permit the withdrawal of the headed end of the can body. Thiswithdrawal of the headed end of the can body is accomplished by the rollj traveling within the inwardly inclined portion of the slotted plate J,or between the points 25 and 26. The raised retaining plate,

blade or paddle G3 bears against the free proi jecting end of the canbody in order to prevent lateral displacement thereof as the oppositeend is forced within the flange of the retained can head. As the roll h2moves from off the cam K2, the movable section ofthe can head holder l2is closed gradually. The position of the can head holder and clampingjaws for the can body, after the movable section hasjbeen raised and theheaded end of the can body removed, is clearly shown in Fig. 7, it beinga horizontal one.

As the clamping jaws are thrown into a horizontal position and theheaded end of the can body removed fromwithin the can head holder, theretaining blade, plate or paddle Gs is lowered so as to be below theedge of the can body in order to permit the free or unheaded end of thecan body to enter the can head iiange retained within the can headholder l2. Prior to the entrance of the unheaded end of the can bodywithin the flange of the can head retained Within the can head holderI2, the retaining blade, paddle or plate G4 is raised or elevated so asto move above the level of the lower edge of the projecting end of thecan body and press against the outer face of the head placed thereon forthe purpose of' holding the can body firmly in place while a can head isbeing secured upon the opposite end of the can body. This retainingplate, blade or paddle is raised by the lifting of the rod G2, caused bythe roll m2 rieding upon the inclined face of the fixed cam N. As thisrod is being lifted to elevate the retaining plate, blade or paddle G4,the rod G is lowered by the-roll m traveling beneath the flange m2 ofdownwardly inclined fixed cam N2. Consequently when retaining plate G3has moved its full downward distance, re taining plate, blade or paddleG4 will have movedvits full upward distance. The cam N IOO IIO

projects upwardly from plate H3, while the cam N2 is secured to andupwardly projects from plate H2. See Fig. 1.

During this raising and lowering of the retaining plates, blades orpaddles the clamping jaws for the can body are being carried forward ina horizontal position until arm I-I rides upon the upwardly inclinedportion4 of the slotted cam plate H2, or from point 8 to 9, when thelift rods D are forced upward, which likewise elevates that portion ofthe clamping jaws connected therewith by means of the bracket of thelift rods D, while the opposite end or headed portion of the can body isthrown downward at an angle by the lowering of the lift rods D2, saidrods being carried downward by the arm II traveling within thedownwardly inclined portion of the slotted cam plate H5, or from pointl5 to 16. This upward and downward movement of the lift rods causes theclamping jaws to swing at an incline or angle, the free or unheadedportion of the can body, projecting beyond the clamping jaws, beingelevated, the position of thecan body and clamping jaws being theopposite to that illustrated by Fig. 6. As the clamping jaws are beingswung or tilted from a horizontal position to an inclined one, the sameis forced over to the side of the machine, that is, to the right handside, the left hand end of :the can body having been headed, by therollj traveling within the inclined portion of the slotted plate J, orfrom point 26 to 27. This inward travel of the roll j causes the slideframe D to move within the lower edge of the unheaded end of the canbody within the flange of the can head held within the can head holderI3. With the continued forward travel of the endless carrier belt orchain, the arm H rides upon the upwardly inclined portion of the slottedcam plate H3, or from point 17 to 18, which moves the lift rods D2upward, said rods carrying the clamping jaws therewith, through itsconnecting parts, until the same hangs in a horizontal position. As theclamping jaws are thrown,` into a horizontal position the upper edge oftheunheaded portion of the can body is caused to move within the flangeof the retained can head. It will thus be seen that the can body isheaded by inserting the lower edge of the can body within the can headflange and thence tilting the can body over until the entirecircumference of the can body has moved within the flange of the canhead, in this respect beingbeyond cam K2. See Fig. 1. VAs the can headholder I3 is opened the clamping jaws for the can body are drawn to thecenter of the machine so as to withdraw the headed end of the can bodyfrom within the can head holder, by

the roll j traveling within the outwardly inclined portion of theslotted plate J, or lfrom point 28 to 29. This withdrawal of the headedend of the can body takes place while the roll h3 is traveling upon thelevel portion of cam K3. The travel of roll m2 beneath the flange ofdownwardly inclined fixed cam N3 moves rod G2 downward, which carriesthe retaining plate, paddle or blade G4 below the level of the can body.As the truck frame carrying the headed can is carried over the wheels ordisks C C toward the discharge chute M, the roll Z, of clamping jaw liftrod G travels under the flange ot' the downwardly inclined fixed cam Land thus causes the rod to move downward, which movement of said rodgradually opens the clamping jaw and permits the headed can to bedischarged into the discharge chtite.

It will be understood that the mechanism herein described, as relates tothe sliding frame, lifting rods, clamping jaws, and retaining plates, Isecure to each of the truck frames. Consequently it will readily be seenthat the capacity of the machine is only limited by the number of truckframes made use of to constitute the endless carrier belt or chain andthe rapidity with which the endless carrier is caused to revolve ortravel.

So far as I am aware I am the first to devise a machine forautomatically applying a tight fitting outside head to each end of a canbody, provided with clamping jaws for receiving and holding the canbodies during the operation of heading, can head holders, and devicesfor throwing the clamping jaws .at an angle to the can head holders, thehead being applied by first throwing the clamping jaws at an angle tothe can head holders and moving the same laterally so as to place thelower edge of the can body within the flange of the can head while thecan body is held in an inclined position, and thence forcing the entirecircumference of the can body` within the flange of the can head bybringing the body into a horizontal position. Consequently I wish to beunderstood as clai ming broadly this feature.

I am aware that minor changes may be made in the arrangement of partsand details of construction without departing from the nature and scopeof my invention.
